T 0 alliwho'm it may concern:

Be it known that I, FAUSTIN PRrNz, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Grain and Seed Separators; and I do declare the following to be a full, clear, and exact description of the in vention, such. as will enable others skilled in. the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to grain separators,

- more particularly for the separation of small round seeds or grains.

It has for its object to provide such a separator that will have larger capacity for separation than previous constructions, and 1n which the separatiomwill be more thoroughly effected.

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter more particularly described and then sought to be clearly defined. by the claims, reference being had to the accompanyin drawing forming a part hereof, and

in who 1 Figure 1 is a plan view of the machine; Fig. 2 is a similar view with the top pan omitted, and arts in section; Fig. 3 is a vertical section t ough the machine, and Figs. 4, 5, 6, 7 and 8 are detail views.

In the drawing, the numeral 1 designates a frame formed of timbers bolted together and provided at its lower portion with a cross timber 2 in which is suitably stepped, for instance in aboxing 3, an upright rotata ble shaft 4 passing through a cross timber 5 at the upper art of the frame and having a boxing or col ar 6 through which the shaft passes, the shaft at its upper end being provided with a bevel wheel 7 with which meshes a bevel pinion 8 mounted on a cross shaft 9 journaled in suitable boxes 10 and having a ulley 11 to which power will be transmitted fiom a suitable source so as to impart a slow rotary movement to the upright shaft.

The upright shaft carries any desired number of concave pans 12, two being illustrated, each of which is su ported by arms or spokes 13 suitably secured to the s aft. Each pan is formed of an inner late 14 and an outer plate 15, the outer p ate preferably being 1 given somewhat greater pitch or inclination than the inner plate. At the adjacent edges of the two plates of each pan there is formed a space or opening 16 between the plates, which in practice may be of an inch, more or less, and the inner edge of the upper plate may be and prefcralfly is formed with an overhanging ledge 17 which will serve to prevent materialfrom passing upward from the inner plate onto the outer plate and to cause said material to pass through. the opening formed as described in the pan. The lower portion of the pan adjacent to the vertical shaft will he formed with. a central 0 )ening or eye 18, the pan at such point being formed with what for convenience may be termed a spout 19 which preferably is made conical or funnelshaped. The space between an upper and a lower pan, around the shaft, is inclosed by a conducting tube or spout 20, which may be stationary, or revolve with the pans, so as to conduct the seeds or round grains, mustard or other seed, discharged from one pan down to an inclined trough 21 by which they will be conducted off.

At one side of the frame is an upright shaft 22 carrying distributing plates 22, one for each pan, said shaft deriving motion through a chain or other form' of belt 23 passing around a pulley 24 on said shaft and around a pulley 25 on the upright shaft 4. The material containing the seed or grain is fed to each distributor from a s out 26 from which a s out 27 of smaller cfimensions leads to eac distributer plate, each spout 27 being provided with a telesco ic end ortion or nozzle 28 which can regu ate the cod to the plate by raising or lowerin the nozzle to control the amount of materia to pass on to each plate. For the purpose of feedin the material in a thin stream from each istributing provided for each plate said scraper preferably being curved as shown and su ported by having one end thereof oonnecte to one of the cross timbers of the frame as illustrated.

For the urpose of directing the material in certain esired directions over each an, a series of scrapers or deflectors are emp oyed. One of these deflectors is designated by the numeral 30 and extends obliquely in the direction of rotation of the pan from the outer edge thereof to the inner edge of the outer plate, or to the point where the inner plate of the pan is spaced from the outer plate of theplate to its respective pan, a scraper 29 is an, said scra er being su orted by an arm 31. The secr ind defleeto i 32 extends obli uely in the other direction, somewhat in advance of the deflector in the direction of rotation of the pan and has one end terminating quite close to the opening between the two plates of the pan and covers about onethird of the cross sectional area of the inner plate of the pan. The third deflector 33 extends in the same direction as the second deflector, in advance thereof, and has its lower end terminating practically at the inner edge of the plate while its other end terminates a short. distance back from the opening between the inner and outer plates of the pan. The deflectors 32 and 33 are supported respectively by the arms 34 and 35. Each of these scrapers or deflectors is composed of a rigid member 36 of wood or other material bolted to its respective arm and provided on its lower edge with a flexible strip 37 preferably of felt about a} of an inch. thick and provided with a weight 38 which may be of metal so that the deflector will bear snugly against the surface of the pan and conform to any irregularities in the surface thereof.

While ordinarily the upright shaft 4 will stand vertical yet at times it may be desirable to give it a slight inclination, and to enable that to be done two of the upright timbers of the frame are formed at their lower ends with a slot 39 so as to straddle a cross I timber 40 which will be provided with metal faced blocks 41 against which will bear adjusting screws 42 passing through the cross timber 43 of the frame so that one end of the frame may be raised or lowered to give the desired inclination to the upright shaft 4. This may be varied from zero to two inches, more or less, as desired, although as stated ordinarily no inclination will be needed.

In operation, the material containing the grain or seed is delivered from the feed s out onto the rotating feed. distributing p ates from whence it passes in a thin stream onto the several slowly revolving pans. From the pan, the small round seeds or grains roll down the inclined surface of the pan and through the eye down tothe inclined delivering spout at the bottom of the machine.

- The seeds which are not round and any material mixed with it, passes only part the way down and comes to astateof rest and is carried in the rotation of the pan around to the first scraper or deflector 30. This scraper deflects the material and causes it to pass from the outer plate of the pan down onto the lower plate thereof, the round seeds rolling down to the central opening through which they escape, and the material not rolling down and caught by the second scraper 32 is deflected u wardly and passes out through the opening between the two lates and is received by an inclined trough 44 (one of said troughs being provided for each pan).

The material which slides down the inner 'pan below the scraper 32 comes to a state of scraper and. when they pass the same they roll down and pass through the center opening in the inner pan. Theother material slides on the inner pan after passing the third. scraper but comes to a state of rest before reaching the central discharge opening in the pan, and in the continued rotation of the pan is again brought against the second scraper 32 which directs it through the 0 ening between the two pans. The seeds w ich roll from the outer pan onto the inner pan strike the inner pan, byreason of their momentum at a point below that at which rests the material passing around the upper end of the third scraper 32 and consequently are .not struck by such'material resting on the inner pan near its upper edge.

This construction, in practice, has been found to give the maximum capacity to a separator of this type and to effect most thoroughly the separation of the round mustard seed from other seeds and refuse material.

I have described and illustrated with particularity the preferred details of construction of the several parts but it is obvious that changes can be made which will be embraced within the scope of the appended claims.
